ATTACHMENT FOB HAY-PRESSES.

Specification of Letters Patent.

Application iiled January 31, 1910. Serial No. 541,071.

Vinvented certain new and useful Improvements in Attachments for Ha Presses; and I do declare the following to e a full, clear, and exact description of the invention, such as will enable others skilled in the art to which, it appertains to make and use the same.

This invention relates to improvements in attachments for hay presses.

The object of the inventonis to provide an im roved construction of plunger for hay ba ing presses having means whereby a hole will be formed through the bale, thus providing for the pro er curing of any hay `which may not have een thoroughly dried when baled.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and ,arrangement of parts as will be more fully described and particularly pointed out vin the ap ended claims.

In t le accompanying drawings, Figure 1 is a side view of a portion of a hay press showing the ap licati'on of the invention, parts being brolen away and in section; Fig. 2 is a central vertical sectional view of the plunger on an enlarged scale; Fig. 3 is a central horizontal sectional view of the same; Fig. 4 is a perspective view of a bale of hay showing the hole formed therethrough by the attachment. y

Referring more articularly to the drawing, 1 denotes the Ealing chamber of a ha press, 2 denotes the plunger operating ro the end of `which has secured thereon a plunger head 3 which is slidably mounted in the balinv chamber. The plunger rod 2 iS connecte with any suitable operating mechanism (not shown).

The plunger head 3 may be of any suitable construction but is here shown and preferably consists of a plate 4 havin on its upper end a right angularly bent fange 5 and 0n its lower end right angularly bent guide ngers 6. In the center of the plate 4 is secured a core pin 7 having a tapered or conical-shaped forward end, said core pin being adapted to be forced through the hay while being pressed in the baling chamber by the plunger head, thereby forming a hole or passage through the bale to permit the free circulation of air through the latter, whereby the hay will be dried and cured after being balcd. 'lhe outer end of the pin projects beyond the rear or out-er side of the plattl 4 and said projecting end of t-he in is preferably providedwith a flattened cad, us shown.

Secured to the rear or outer side of the plate 4 are rectangular guide frames 8, in the. vertical portions of which are formed guide passa es 9, which aline with similar passages 10 ormed in the plate 4 adjacent to its opposite side edges. With the passages 9 and 10 are slidably engaged guide rods 11 on which, adjacent to the rear side of the plate 4, are arranged stop nuts 12. On the rods 11 between the nuts 12 and the vertical portions of the guide frames 8 are arranged spiral springs 13, the pressure of which is exerted to project the ends of the rods 11 beyond the outer face of the plate 4, as shown. To the outer ends of the rods 11 is rigidly secured a guard plate 14, on the upper edge of which is formed a rearwardly rojecting gua-rd flange 15, which is slida ly engaged with the flangel 5 on the upper edge of the plate 4. In the center of the guard plate is formed a circular aperture through which the core pin 7 is adapted to project when the guard plate 14 is forced back by pressure against the hay when the plunger is projected.

When the plunger is retracted, the springs 13 again force the guard plate outwardly over the core pin, thus permittin the latter to retract and holding the hay ack. The flange 15 on the upper edge of the guard plate prevents the hay from being forced in between the guard plate and the plunver plate 4. The guard plate and flange a so prevent the hay from catching onto the end of the core pin.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without. requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without. departing from the principle or sacrificing any of the advantages of' this invention as deh'ncd in the appended claims.

Patented Sept. 20, 1910.

Having thus described my invention, what] claim is In a hay press, a balnug` plunger comprising a plunger rod, a plunger head secured to said rod, a core pin arranged in said plunger head to form a assage through the bale of hay formed in t e press, and means to 'prevent the hay from catching von said core pin during the process of Ifeeding the hay to the bales.A

, 2. In abaling` ress, a plun er compris.- ing a plunger roda plunger ead secured thereto, a core pin secured to said head and adapted to be yprojected thereby through the charges of hay when lforced luto-the press thereby providing a- Ventilating assa e through the bale, a `guard plate yie ding y connected to said plunger head and adapted to prevent the hay from catching on and interfering withthe operation of t e plunger head and core pin. l

3. In a hay baling ress, af plu er comprising a plunger ro a plun er eadsecured to the end of said rod, said head comprising a plate havingon its upper edge a right angularly rearwardly projecting flange and on its lower edge right angularly projet-tang guide finwers, a core foi-nung pm secured to said plaunger plate, guide frames'v 30 plunger plate, guide rods slidably engaged secured to the rear or outer side of Said of said plate and adapted to engage t e flange on said plunger plate whereby hay is prevented from entering hetweensaid guard and plunger plates.`

In testlmony whereof I have hereunto set t I my hand in presence of two subscribing witnesses.
